Question

$18a^3{b}^3{c}^2÷6abc=$

• A. $2a^2{b}^{2}c$
• B. $3a^2{b}^{2}c$
• C. $3a^{2}bc$
• D. $3abc$

Answer 1

The correct option is B

$3a^2{b}^{2}c$

Given:

$18a^3{b}^3{c}^2÷6abc$

$=\frac{18a^3{b}^3{c}^2}{6abc}$

$\because \frac{a^n}{a^m}=a^{n-m}$

$\Rightarrow \frac{18}{6}\times a^{(3-1)}{b}^{(3-1)}{c}^{(2-1)}$

$=3a^2{b}^{2}c$
